Unit digit of the square of 26094

Here we will show you two ways of finding the unit digit of the square of 26094. First, we will define what the unit digit of the square of 26094 means. Next, we will find the unit digit of the square of 26094 using the Rule Method, and then we will find the unit digit of the square of 26094 using the Math Method.

The last digit (one digit) of the product you get when you multiply 26094 by itself is the unit digit of the square of 26094.

Rule Method
The unit digit of any square will never be 2, 3, 7, or 8. It can be only 0, 1, 4, 5, 6, or 9. Furthermore, the unit digit of the square of a number depends on its units digit. In other words, the unit digit of the square of 26094 depends on 4, because that is the last digit in 26094. Here are the rules:

Rule A) If the unit digit of a number is 0, then the unit digit of the square of that number is 0.

Rule B) If the unit digit of a number is 1 or 9, then the unit digit of the square of that number is 1.

Rule C) If the unit digit of a number is 2 or 8, then the unit digit of the square of that number is 4.

Rule D) If the unit digit of a number is 5, then the unit digit of the square of that number is 5.

Rule E) If the unit digit of a number is 4 or 6, then the unit digit of the square of that number is 6.

Rule F) If the unit digit of a number is 3 or 7, then the unit digit of the square of that number is 9.

The unit digit of 26094 is 4, therefore Rule E applies, and the unit digit of the square of 26094 is 6.

Unit digit of the square of 26094 = 6

Math Method
The unit digit of the square of a number depends on its units digit with this method too. Here you multiply the unit digit of the number by itself, and then look at the unit digit of that product. Again, the unit digit of 26094 is 4, so you multiply 4 by itself, and then look at the unit digit to get the answer once again:

4 × 4 = 16
Unit digit of 16 is 6.
Unit digit of the square of 26094 = 6

Of course, instead of using either of the methods above, you can multiply 26094 by itself if you have the time or a calculator, and then identify the unit digit to get the answer to the unit digit of the square of 26094. We did that below to double-check that our answer is correct:

26094 × 26094 = 680896836
Unit digit of 680896836 is 6.
Unit digit of the square of 26094 = 6
